Do you crimp wire ferrules?

For ferrules, you crimp the metal tubing itself onto bare wire while for the crimp connectors you crimp part of the barrel onto the insulation and the other part on the stripped wire end.

Who invented ferrule?

That all changed when J.B. Ostrowski patented his aluminum pencil ferrule. Ostrowski strengthened the aluminum ferrule by adding small serrations to the outside of it – a simple and affordable solution that made aluminum a feasible material for producing ferrules.
